DESCRIPTION

The Swirl Control Valve (SCV) position sensor is a non-contact type sensor.

The position sensor measures the opening angle of the swirl control valve. The sensor is reliable and accurate, as it is electrically controlled by Hall-effect elements.

Tech Tips

When DTC P2014, P2016 or P2017 is output, use the GTS to confirm the IAC Sensor Voltage (swirl control valve position sensor output voltage). Enter the following menus: Powertrain / Engine and ECT / Data List / All Data / IAC Sensor Voltage.

IAC Sensor Voltage Malfunction
0.2 V or less
  • IAC1 circuit shorted

  • VC circuit open

4.8 V or higher
  • VC and IAC1 circuits shorted

  • IAC1 circuit open

  • E2 circuit open

MONITOR DESCRIPTION

The ECM IAC1 terminal voltage increases in correlation with the opening angle of the swirl control valve. When the swirl control valve is fully closed, approximately 0.69 V is applied to the IAC1 terminal. When the swirl control valve is fully open, approximately 3.518 V is applied to the IAC1 terminal.

When the output voltage of the IAC1 terminal deviates from the standard range, the ECM determines that a malfunction has occurred in the position sensor and stores a DTC.

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the engine switch on (IG) and turn the GTS on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  4. Turn the engine switch off and wait for at least 30 seconds.

  5. Turn the engine switch on (IG) and turn the GTS on.

  6. Wait 0.5 seconds or more.

  7. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

  8. Read the pending DTCs.

    Tech Tips


    • If a pending DTC is output, the system is malfunctioning.

    • If a pending DTC is not output, perform the following procedure.

  9. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

  10. Input the DTC: P2014, P2016 or P2017.

  11. Check the DTC judgment result.

    GTS Display Description
    NORMAL
    • DTC judgment completed

    • System normal

    ABNORMAL
    • DTC judgment completed

    • System abnormal

    INCOMPLETE
    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions

    N/A
    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

CAUTION / NOTICE / HINT

Tech Tips


  • If other DTCs relating to different systems that have terminal E2 as the ground terminal are output simultaneously, terminal E2 may have an open circuit.

  • Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. PERFORM ACTIVE TEST USING GTS (CONTROL THE SCV DUTY RATIO)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG) and turn the GTS on.

    3. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the SCV Duty Ratio / All Data / IAC Sensor Voltage.


      Powertrain > Engine > Active Test
      Active Test Display
      Control the SCV Duty Ratio

      IAC Sensor Voltage
    4. Check the value of IAC Sensor Voltage while changing Control the SCV Duty Ratio from -100 to 100% (or from 100 to -100%) using the GTS.

      Standard
      The value of IAC Sensor Voltage remains between 0.2 to 4.8 V while Control the SCV Duty Ratio is changed from -100 to 100% (or from 100 to -100%).
